Scenario-based assessment of the potential effects of alternative dam construction schemes on freshwater fish diversity in the lower Mekong Basin
Research grant
- Project Description
This research focuses on the effects of existing dams on freshwater fish and their environment in the lower Mekong Basin, an area known for its extremely high degree of biological diversity, and on the environmental risks presently by dams under planning. More concretely, we direct our attention to as many migratory fish as possible, gathering existing data on the Mekong Basin environment and its freshwater fish from a variety of related organizations for GIS (geographic information system) compilation. We also conduct onsite surveys in three lower-Mekong countries, sampling fish and chemically analyzing their otoliths (inner ear) to reveal migratory routes. We next evaluate the impact of existing dams and assess the ecological risk of those under planning by means of statistical modeling, with the results to be reflected within specific siting scenarios (e.g., relocating planned construction sites, identifying alternative sites, etc.).
